I have been buying and selling on ebay for years with little hassle and very very few issues either way till recently.
I have now been forced to use paypal and it sucks. I sold a new cylinder head today for £300 and had to refund the money as I couldn't take it out of paypal. I need to set up a direct debit to paypal to get it and there is no way on earth I am setting this up to a company you can't contact plus why should I, they already have the bank account details!
I have around +800 feedback and have had enough, the latest changes mean I think it is time to stop using it and look for an alternative, even if its back to Exchange and Mart.
The only real hassle I have ever had was selling something secondhand for a couple of hundred quid which the guy knackered the third time he used it (he actually told me this in his compliant) and wanted a full refund including postage. After telling him to get lost and being threatened a bit he went away, eventually! I mean imagine breaking something, admitting it and then expecting all your money back including postage costs!
